In the preview for season seven, episode two, Arya appears to be confronted by a wolf that many fans are hoping is her former direwolf, Nymeria. And they lost their minds:

Fans haven't seen Arya with her direwolf since season one when Arya forced Nymeria to run away because she feared for her direwolf's life after she attacked Prince Joffrey. It was a heartbreaking scene that didn't bode well for the Starks or Arya on their way to King's Landing.

Though that's the last we saw of the direwolf on the show (so far), in the books, it appears as though Arya has "wolf dreams" where she is able to warg into Nymeria's body, just like what her brother Bran could do with his direwolf Summer. It's implied from those dreams, as well as in tales across Westeros, that a ravenous wolf pack is terrorizing the Riverlands, helmed by a great huge she-wolf — we assume this to be Nymeria.

"During my visit, wolves described in the script as 'skinny and mangy' showed up to the shoot looking fluffy and lustrous," Time reporter Daniel D'Addario wrote in a feature.

Seeing Nymeria would mean a lot to direwolf fans. The only other living direwolf on the show is Ghost — Jon Snow's albino companion — after Bran's direwolf, Summer, was killed by wights at the end of season six.

And while we do hope to see more of Ghost on season seven, the prospect of having Arya and Nymeria reunite is way, way cooler.
